“Judelson, Giordano & Siegel, CPA, PC are more responsive, accessible and easier to deal with than other firms. They did some outstanding work in redesigning reports for our partners.”

“JGS is very good, and very responsive. They promptly return phone calls and offer a quality level of service and tax expertise. I’ve found that I’ve been making more money and paying less in taxes legally. To me that’s exceptional.”

“They know monthly what is going on. They know everything about the business, my personal finances, and my relationships with employees. There is nothing that I hide from them. They are helping with full estate planning and business acquisition. They helped me leverage the numbers in the acquisition and helped in negotiating the cost of the business. They have enabled me to get the financing ...

Every phone call is important to Bill. I think of him as more of a friend than an accountant. The personal touch is important. I’ve been able to call Bill at any time, at home, and he has responded to me. He’s made multiple visits, and he has always been very professional. He’s been very astute to whatever arises and deals with it immediately. And he’s always made me feel c ...

We wanted experience in construction, a clear and accurate ability to communicate the financial condition of the company. We have Gary look at each deal to give us the tax implications and advice on negotiations. We’ve been audited by the IRS and NYS sales tax department and as difficult and arduous as the process can be Gary Cassiello and Judelson, Giordano & Siegel, CPA, PC have preva ...

As a young three year old company in 2006, we needed the expertise of a CPA firm that could communicate openly and respect our uniqueness to help us structure our organization and financial recording processes to make American Petroleum one of the fastest growing environmental construction companies in the Mid Hudson Valley. Judelson, Giordano and Siegel proved their worth to us (now in our fifth ...

“Judelson, Giordano and Siegel are far superior to the accountants I have had in the past. The cost, their ability and the direction they offer you, places them above the competition. Their expertise regarding my business and my retirement needs was amazing! They are incredible negotiators and helped me tremendously with the sale of my business.”

“The estate planning JGS did was outstanding. They work well with the attorney to get it done. I recommend clients to them.”

“JGS has been the best. They ask all the right questions. As we’ve gone along in business, we’ve acquired a number of companies (we’ve done 8 or 9 acquisitions) and everyone was different. It was Frank’s foresight, knowledge and clear thinking that made every one of them successful. We always recommend them to others.”

“JGS is beyond comparison to other firms. They are very proactive and knowledgeable. We have a real comfort level working with them. They made the transfer of ownership in our family business seamless, and they have all the information, pros & cons on the tax issues.”

“JGS is superior because of the personalized service they provide. Bonnie Orr is wonderful; she does everything for us. With other accountants we would leave a message and it would take a long time to get a response. Bonnie calls back very promptly.”

“There’s a certain personal touch from JGS that other firms lack. JGS doesn’t forget who we are. They were extremely helpful when I detected some embezzlement by one of my employees. They helped me work through everything including filling out the timeline I was going to present to the police. JGS has set a new standard for what an accountant should be. They are like part of the ...

“Frank is a quintessential pro company individual. He does not look at individuals within the company, but looks for what is best for the company as a whole… Frank is a tremendous negotiator; he makes things happen. In contrast to other professionals who turn things down; he makes things come together by negotiating on behalf of the company, not individuals. They are excellent not only ...

“I expected them to be great and they have been. It’s not only their competency, but the relationship. They really know their stuff, and I enjoy meeting with them. They are not your typical boring accountants. They are like a business partner. They open your eyes to more strategies. I recommend them on a regular basis.”

“Bonnie is a consummate professional. She dots every “i” and crosses every “t”. She never allows me to fall into a place where I am vulnerable. I sleep very well at night because of Bonnie. She saves me money on taxes; prevents me from pitfalls. She is on the top of her game. She never lets the ball drop.”

“The level of service JGS provides is outstanding. I give them a 10! I don’t give out big marks that easily, but they are good and save me taxes.”

JGS orchestrated a buy-out deal between my father and I that was both brilliant and creative. We couldn’t have done it without them. My father and I had other accountants look at our situation, but they just didn’t have the expertise of the JGS team. When it comes to buy outs, acquisitions and mergers Judelson, Giordano and Siegel is the firm I would recommend to anyone.

“Bonnie, I can’t thank you enough for your help in handling all of this so quickly and professionally. Managing the various aspects of this estate from such a distance has been terribly difficult, but working with you has taken one large part of the burden off my shoulders.”

“I’ve known Bonnie Orr since the middle 1990s … that would be 22+ years. She has managed every aspect of my small business planning through multiple corporations, LLC’s, marital dissolutions and tax jurisdictions. It never ceases to amaze me how she always knows what to do and can answer a question, without even hesitating, on the most complex of business tax issues. Never have I felt vulner ...
